I didn't want to insist on that because I know that OpenWrt devices are
generally strapped for storage. Also, I never managed to build an OpenWrt
by myself, plus my only OpenWrt device is helping me send this email, so
I can't be of very much help on that front, I'm afraid. But I'm happy to
see Martin take the initiative, and the encouragement from you.

I was definitely suggesting this as the easy way out, as you can put
Debian on an ext4 formatted USB stick. Debian 10 should definitely be
enough, as these selftests don't use the latest and greatest features
added to iproute2 IIRC, but it's concerning on the other hand that
maintainership for the debian-mips port was dropped. Are you closely
involved with the topic, do you know what's blocking the upgrade?
